APPARATUS FOR THE STERlLlZATlON OF WATER BY MEANS OF ELECTRIC CURRENT.

Specification of Letters Patent.

Iatented Nov. 27, 1906.

. To all whom it may concern.-

Be it known that I, MARrUs OTTO, of 5 Avenue du Bois-de-Boulogne, Paris, France, have invented a certain new and useful Apparatus for the Sterilization of Water by Means of an Electric Current; and I do hereby declare the followin to be a full, clear, and exact description of t e invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The two difiiculties which hinder the purification of small quantities of water by means of ozone are, on the one hand, the necessity for the production of the required quantity of ozone by means of apparatus sufficiently simple and economical and, on the other hand, the provision of an efficacious process which will place water and ozone into contact with one another without requiring the employment of complicated and costly apparatus.

The present invention relates to a system of operationwhich maybe described as electric filtration, which is adapted to overcome these difiiculties perfectly.

The invention consists in principle of a simple arrangement by means of which the ozone or ozonized air necessary for the sterilization of the water is drawn into the producing apparatus by the action of the same stream of water as that which is to be sterilized, the regulating and setting in motion of the stream ,of water and the stream of ozone being performed by hand or automatically by means of one and thesame mechanical contrivance.

. The accompanying drawings show as representative examples various practical forms for the carrying out of this invention.

Figure 1 is an elevation, partially in section, of one form of construction, of which Fig. 2 represents in section the device for automatic stopping and starting, Figs. 3 and 4 being the diagrams corresponding to the extreme positions of this device. Figs. 5 and 6 represent in front and. side elevation, respectively, a similar apparatus of small capacity. Figs. 7 and 8 represent in front elevation, partially in section and in side elevation, respectively, an apparatus without the Gay-Lussac column to be presently referred to. Fig. 9 is a section of the stopping and starting valve.

In all the various arrangements the water to be sterilized, being, if necessary, first of'all cleared from solid matter which it may hold in suspension, is admitted into a s rayer a, which is in communication also with t e ozonegenerator.

The sprayer, which is a kind of injector, consists, as is shown in section in Fig. 1 and more particularly in Fig. 7, of a ch ber 1, into which open opposite one anot er two conical passages 2 and 3. y The chamber lreceives ozone or ozonized air through a pipe 6, while the water to be sterilized entersfrom the pipe 0 into the conical passa e 2. The water and sterilizing-gas drawn inIiy this water are discharged through the conical passage 3.

The apparatus (1 for producing ozone can be of any known construction. In the example of 1 the ozonizer d is a rotatin fore-mentioned pipe I) is led. The water under pressure flowing through 0 causes suction in the pipe b, and consequently in the column f. The water having been finely div ded in the sprayer a escapes impregnated with gas through the cone 3 and the pipe g. In the chamber 6, Fig. 1, a separation is effected of the excess of ozonized-air, which escapes by the pipe h. In the apparatus in F1 1 the water be' freed from the excess 0 air descends by t e pipe 1', through a rose and falls into the column f, where it encounters for the second time an ascending stream of ozone.

The sterilized water escapes through the pipe 7c and falls into a reservoir m, fromwh ch it can be drawn off by means of a stop-cock'n. In this reservoir is placed afloato, attached to a rod 1), which is guided at q and r. On this rod are secured two fingers s and t, which according as the level of the water is too high or too low, respectively, suitably operate the lever u of the plug of a three-way stop-cock 'v. This stop-cock is connected by a branch a to the feed-pipe 'y of the water under pressure and by a pipe 10 to the stopping and starting apparatus 2.

7 18 an escape or overflow pipe leading from Y the stop-eockv.

The apparatus 2, Figs. 1 and 2, consists of a closed cylinder 8, the end of which is con-, nected to the pipe w. In this cylinder at piston 9 operates under the action'of a spring 10 collar 23, secured to the rod of the valve 18,-

tends to return the valve to its seat'as the contact 12 removes the pointer 17 from the end of the valve-rod, thereby stopping the flow of water through the pipe 6.

Normally the electric current passes into theozonizer by means of the contact 13, so

' valve 18 wil that ozone is produced at the same time as the valve 18 is open, and water, coming from the pipe y and the pipe 21 passes from 19 into 20 to rise through the pi ecto the sprayer a. In this case the stop-000 '0 is in the position shown in Fig. 3. When the reservoir m is about to'become full of sterilized water, the float b, rising into the position shown in Fig. 4, operates the lever u of the stop-cock by means of the finger s, whereon the water under ressure will enter by the pipe to into the cy inder 8 and forcingthe piston 9 compress the spring 10. The contact 12 will thereby be driven to the non-electrified knob 16. a The result will be that the current will cease to flow into the ozonizer, the valve 18 will close, and the apparatus be entirely suspended from working. When the float 0 sinks suflioiently for the finger i to press down the lever u into the position shown in Fig. 3, the water previously admitted to the cylinder 8 will escape through the pipe 7. The pressure being relieved in 8, the contact 12 Wlll return to the position shown in Fig. 2 and the again open, and so on. In the form of construction shown in Figs.-

I. 5 and 6 the ozone-generator d inclosed in a box of rectangular shape containing a transformer and operated directly by the electric suppl of the district;

.Re erring to Figs. 7', 8 and 9, the apparatus here shown is somewhat modified 111. form from'that shown in theother figures. In this form the Gay-Lussac column is omit;-

- ted and the waterafter being ozonized by p through the 5- being sprayed throughthe' sprayer a falls pipe. g into a receptacle m, from which 1t' asses off by the outlet eJ-gtt will also be seen'from these figures senior that in place of the automatically-operated starting and stopping mechanism a handoperated valve 50 (see Fig. 9) is inserted in the pipe 0, which valve is kept normally ceiver m and rising therein flows out by the outlet 'n in a constant stream until the valve 50 is allowed to be returned to its seat by the returning influence of its spring 51. Any form of ozone-producer, such as (Z, may be em loyed in this modification.
